MSC WEEK 9 PLIF TLIF EXAM REVIEW UPDATED
QUESTIONS AND ANSWERS
What are TLIF cages made out of? - CORRECT ANSWER✅✅✅3D printed titanium
Why is a TLIF cage more challenging than the plates?
- cage is rectangular and easier to place anteriorly
- support the posterior spinal column
- trying to position the cage anteriorly and at the midline to support the load of the anterior spinal
column - CORRECT ANSWER✅✅✅trying to position the cage anteriorly and at the midline to support
the load of the anterior spinal column
Helical flange technology is...
- 90 lbs per inch

- set screw
- deform to the rod
Does bullet nose feature benefit...
, - fill lordotic space
- designed for larger disc spaces
- prevents cage migration
- self distracting in collapsed disc space - CORRECT ANSWER✅✅✅- self distracting in collapsed disc
space
Benefits of expandable cages are...
- safer b/c passing a collapsed cage across neural elements
- typically less expensive
- can it be expandable in the disc space as surgeon sees fit
- req an additional step for locking
- help induce lordosis - CORRECT ANSWER✅✅✅- safer b/c passing a collapsed cage across neural
elements

- help induce lordosis
Benefits of a titanium coated roughened surface are...
- anti migration
- minimal end plate prep
- less distraction
- osteoconductive/ scaffold - CORRECT ANSWER✅✅✅- anti migration
- osteoconductive/ scaffold
